Hi Emmanuel, With the latest update of swt4-gtk to 4.18.0-1 I am seeing a problem in loading the library. After a little debugging it seems its not finding a symbol. /usr/lib/jni/libswt-pi3-gtk-4940r23.so: undefined symbol: gdk_texture_new_from_file Then it tries to find "/usr/lib/jni/libswt-pi4-gtk.so" which is not present and so the application fails. Any ideas? -- Regards Sudip
